When I try to upload a CSV file "From Web", I receive an error that states the 'table has no columns'. I even get the error when I try to upload the sample file provided with the plugin, so it is not a formatting error. Yet, the upload from computer works fine. My CSV is a dynamic file that needs to be updated on refresh, so I need to use the "from web" loader for CSVs.

I'm not using Google spreadsheets, my file is a properly formatted CSV in a readable folder on my site. For example, your area chart sample does not work when using the "from web" function. Here is the link:

Were you able to resolve this issue? I'm having the same error on my WordPress site - "Table has no colums" using the From Web option. The source CSV is a Google spreadsheet, super-simple. I was hoping your plugin would allow me to display a Google-based chart dynamically, updating as the source spreadsheet updates.
